ment to window frames of different widths,

and adapted for disposal either above the u per or below the lower sash, and that will a low free passage of air to a room but will positively preclude entrance of rain, whereby with houses that are not equipped with shutters it will not be necessary to close the windows during a rain storm, thereby obviating a source of much discomfort to the occupants, especially if the storm be one of long duration. Furthermore, to render it possible for a house holder to air the house during her absence without being subjected to worry from fear that rain will beat in the windows.

With the above and other objects in view,

' as will appear as the nature of the invention is better understood, the same consists, generally stated, in a window shutter comprising two sections each embodying angularly-diS- posed slats of the same general construction as those of an ordinary shutter, the slats being adapted to overlap and have sliding movements relatively to each other, whereby to'adapt the structure to window frames of different widths.

The invention consists further in the various novel details of construction of a window blind, as will behereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification and in which like characters of reference indicate corresponding parts,Figure 1 is a view in front elevation, partly broken away, of a window blind constructed in accordance with the present invention. Fig. 2 is a vertical longitudinal sectional view on the line 22, Fig. 1, and looking in the direction of the arrow thereon. Fig. 3'is a fragmentary detail view of a portion of the structure shown in Fig. 1.

The blind comprises two sections designated, generally, 1 and 2. One of the sections, in this instance, the section'2, is composed of a stile 3 and a guide 4, each of which 1s provided with obliquely-disposed slots or seats 5 and 6, the latter being shown in Fig. 3, to receive the slats 7.

As shown in Figs. 2

across the stile and guide 4 but terminate short of one edge thereof, and the slats 7 project beyond the forward edge of the parts in order to be more effective in shedding rain, and also to sim lify the construction ofthe article, as it wilFbe easier to out the seats as shown, which may be done by a saw, than it would be to mortise them in -the ordinary manner.

referred manner as by nails 10 or if preferred a suitable adhesive may be employed, or both an adhesive and nails.

11 that is formed of astrip of metal prefera galvanized iron secured at its upper end 12 to the guide, thence deflected laterally, as at 13, to aflord space for the slats to move, the lower end of the keeper being inbent andsecured to the lower end of the guide at 14.

The section 1 embodies a stile 15 of the same construction as the stile 3 and in which are rigidly secured the slats 16 in the same manner as that above described. These slats are adapted to overlie the slats 7 of the section 2 and to work in the slots 5 of the 1.1 serving to prevent the slats from having any rocking motion relatively to each other and also to maintain them in alinement, and in a great measure to relieve the holding means 10 from undue strain.

From the arrangement described it will be seenthat the two sections land 2 may be readily adjusted so 'as to fit any size of window frame, such adjustment being indicated by dotted lines in Fig. 1, and further that the blind may be placed under the lower sash or above the upper sash, as may be preferred,

sought. In order to stay the stile 3 and guide 4 against relative movement or any tendency to yield when the sections are moved inward and outward in order to accommodate them to brace 1'7 is employed which is by preference 'made of a strip of galvanized iron and is firmly secured to the back of the stile and to the guide, as shown in Figs. 1 and 2.

It will be seen frornthe foregoing description that there is a common and. underlying feature present in each of the forms shown,

The guide 4 has combined with it a keepier and 3, the seats 6 do not extend entirely The slats 7 are secured in the stile 3 in ahy guide, as clearly shown in Fig.- 2, the keeper and thereby positively secure the objects the window frame, a

namely, that of permitting adjustment of the having obliquely disposed seats open at one I ssi,4ss

through the seats of the guide, means for holding the slats in the latter seats, and a brace connecting one of the stiles and the guide.

In testimony that I claim the foregoing as my own, I have hereto alhxed my signature in the presence of two witnesses.
